Port-a-Pottie Deodorizer

[SCSTWG]

Any suggestions on which portable toilet deodorizer to purchase and where? I think I have used the Coleman product from Wal-Mart in the past, but was hoping to buy something in a larger quantity to be more cost effective and to run out less frequently. I knew when I bought the boat that having 3 little girls meant that having a head onboard was mandatory.......let's just say that I underestimated it.
